God explains how future priests will be clothed and how the altar will be continually purified. The priests are sustained by what is offered to God. God takes responsibility for those who serve Him. When God calls, He also provides.

It reads in Exodus 29:29–37 Easy: Aaron’s special clothes will belong to his descendants after he dies. When they too become God’s special servants as his priests, they will wear them. After Aaron’s death, his son who becomes priest will first take seven days to serve the Lord in the tabernacle. The new priest must wear the special clothes in the Holy Place for those seven days. Take the male sheep that makes Aaron God’s special servant. Cook its meat in a holy place in the yard of the tabernacle. Aaron and his sons must eat this meat and the bread that was in the basket. They must do this at the entrance of the Tent of Meeting. That meat was part of the sacrifice which made them clean from their sins. It made them God’s special servants as his priests. No other person may eat those things, because they are holy. But if any of the meat from the offerings remains until the morning, you must burn it. Also burn any bread that remains. You must not eat it, because it is holy. Do everything that I have commanded you, to make Aaron and his sons my special servants. Take seven days to do this. Kill a bull each day, as a sacrifice that makes people clean from their sins. Also make the altar clean and pure. Pour oil over it to make it holy for me. Do this to the altar for seven days to make it pure. Then it will be completely holy. Anything that touches the altar will become holy too. 

Father God, You are the One who sanctifies Your people and makes them holy. As You promised to dwell among Israel, dwell among us today. Cleanse our hearts, consecrate our lives, and make us a place where Your presence rests. Let our worship rise continually before You, and may our lives reflect Your glory. We belong to You, and we trust You to make us holy by Your grace. Love You, thank You, praise You and give You all the honor and glory in Jesus Precious Name  Amen.
